IBARTLEY BROWN, OF FORT WORTH, TEXAS.

PLOW-FRAME.

To all whom 'it may concern:

Be it known that l, BARTLEY BROWN, citizen of the United States, residing at Fort Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Plow-Frames, of

, which the following is a specification.

This invention has relation to plow frames, and has for its object to provide a frame of special design and construction to which may be attached plow bottoms or cultivator beams, as desired.

With this object in view, the frame consists of side portions connected together at their tops and spaced from each other, whereby a stalk passageway is provided between them. Each of the said side portions is provided with vertically adjustable bar members which are mounted upon the supporting wheels, the said wheels being adapted to be positioned at either side of the said bar members, whereby the wheels may be outside of the side portions of the frame or within the same, as desired. A tongue is mounted upon the frame, and means is provided for shifting the tongue laterally while the frame is traveling or while it is at rest.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a perspective view of the plow frame; Fig. 2 is a side elevation of the beam. Fig. 3 is a top plan view of the beam.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

The frame consists of a forward cross bar 1 and a rear cross bar 2 which are connected together at their ends by 'side bars 3. These bars are arranged in pairs the members of which are spaced from each other. Bars 4 depend from the ends of the bars 1, 2 and 3 and are also arranged in pairs the members of which are spaced from each other. The bars 4 constitute the corner bars of the frame, and bars 5 are connected at their forward ends with the forward corner bars 4 and at their rear ends with the rear corner bars 4. These bars are located under the bars 3. Bars 6 depend from the intermediate portions of the bars 1 and 2 and are spaced from each other, whereby a stalk Specification of Letters Patent.

passage is provided between the saidvbars 6 which are located at the opposite side portions of the frame. Bars 7 are connected at their forward ends with the forward bars 6 and' at their rear ends with the rear bars 6. Bars 8 are connected at their outer ends with the lower ends of the corner bars 4 and at their inner ends with the lower ends of the bars 6. Bars 9 are connected at their outer ends with the corner bars 4 and4 at their inner ends with the bars 6 at points above the bars 8, the space between the bars 8 and 9 at the rear portion of the frame being greater than the space between the said bars and the forward portion of the said frame. The bars hereinbefore described may be held in proper relation by appropriate or suitable brace rods.

Arms 10 are pivoted at their forward ends between the members of the forward corner bars 4 and extend rearwardly and have their rear ends passing through the spaces between the members of the rear corner bars 4. The said arms 10 are adjustably connected with the forward corner bars 4, whereby their points of pivotal connection may be raised or lowered, as desired. Blocks 11 are adjustably mounted upon the bars 10 and carry spindles 12 which may be disposed at the inner or outer sides of the said blocks, as desired. Supporting wheels 13 are journaled upon the spindles and when the spindles are outwardly disposed, the said wheels are beyond the outer sides of the frame, but when the said spindles are inwardly disposed, the said wheels are positioned between the bars 5 and the lowermost bars 7. Bars 14 are fixed at their lower ends to the blocks 11= and at their upper ends rest loosely between the members of the side bars 3. The members of the side bars 3 lit snugly against the opposite sides of the bars 14, but the said bars are free to move up or down between the members 3, but the members of the bars 3 are suiciently close to the bars 14 to prevent the same from twisting or turning in a horizontal direction. Inasmuch as the bars 14 are xed at their lower ends to the blocks 11 and the said blocks are slidably mounted upon the arms 10, the bars 14 and the blocks 11 will serve to prevent the intermediate portions of the arms 10 from bowing inwardly or outwardly.

Blocks 15 are supported at the upper rear corners of the frame and rods 16 pass through the said blocks. The said rods are adjustably connected at their lower ends with the rear ends of the arms 10, and' hand wheels 17 are screw threaded upon the upper ends of the rods 1G and rest upon the upper faces of the blocks 15. Therefore it will be seen that by rotating the said hand. wheels, the rods 1G will be moved vertically through the blocks and thus the rear ends of the arms 10 may be raised or lowered. Therefore the frame may be positioned at any desired distance from the surface of the soil, or one side of the said frame may be located nearer the surface of the soil than the other' side.

A yoke 18 is mounted upon the upper side of the cross bar 1, and a shaft 19 is journaled upon the cross bar 2. A sleeve Q0 is pivotally mounted at its rear end upon the shaft 19 and its forward portion lies between the intermediate portion of the yoke 18 and the top of the bar 1. A tongue 21 is inserted in the forward end of the sleeve 20. A hand wheel is fixed to the upper end of the shaft 19, and a drum 2st is fixed to the shaft 19 and is located within the sleeve 20. A cable 25 is attached at one end to one end of the yoke 18 from whence it passes through the side of the sleeve 20, thence back to the drum 24 and around the same, thence forward and out at the opposite side of the sleeve 20 and is attached at its other end to the other end of the yoke 1S. Therefore it will be seen that by turning the hand wheel 23 and rotating the shaft 19 that said cable will be moved longitudinally by the drum 211, and inasmuch as the ends of the cable are fixed to the yoke 18, which in turn is fixed to the bar 1, the forward portion of the frame will be swung horizontally under the sleeve 20 and thus means is provided for adjusting the frame at a desired angle with relation to the sleeve and the tongue, whereby the line of draft of the frame may be varied.

A seat post and seat, indicated at 26, is carried upon the cross bar 2 and the hand wheel 23 is within reach of one occupying the said seat. A shaft 27 extends transversely across the frame and is journaled at the upper forward portion thereof. An arm 28 is fixed lto the shaft, and a lever 29 is fulcrumed upon the rear portion of the frame. A rod 50 operatively connects the lever 29 with the arm 28. Therefore it will be seen that by swinging the lever 29 that the rod 30 will be moved longitudinally and the shaft 27 will be partially rotated.

Heads 31 are provided with forwardly projecting lugs which are adjustably mounted thereon and which engage the foremost bars 8 and 9 and which may be adjusted in their positions thereon. These lugs are pivotally secured to the said bars by means of pins 83 which pass transversely through the lugs and the bars. Beams 34 are pivotally connected at their forwaii'd ends with the heads 31. 'The shaft 27 is provided with fixed arms 35, and rods 8G pivotally connect the arms 35 with the forward portions of the beams 34. Therefore it will be seen that as the shaft 27 is partially rotated, as hereinbefore described, the rear end portions of the beams 34 may be raised or lowered. These beams 34C may carry at their rear ends cultivator shovels, in which case the rear end portions of the said beams are left free for vertical movement. However, the beams may carry at their rear ends plow bodies, in which instance links 3T are connected at their lower ends with the rear ends of the beams 34 and at their upper ends are adjustably connected with angle irons 3S which in turn are adjustably supported upon the rearmost bars 8 and 9.

In operation, the frame may be disposed at a desired angle with relation to the line of draft as the contour of the surface of' the soil may require and the frame may be employed for supporting a gang of breaking plows. Then used as a cultivator, the intermediate portion of the frame may straddle,

`a row of plants, whereby the beams Set will be located at the opposite sides of the row, and if the space between the rows is limited, the wheels 13v may be positioned between the bars 5 and the lowermost bars 7. Also, the frame may be positioned at any desired distance from the surface of the soil, and if desired one side of the frame may be nearer the said surface than the other.

Having thus described the invention, what is claimed as new is:

1. A frame including a forward corner bar, rear corner bars arranged in pairs spaced from each other, a lower bar connecting the forward and rear corner bars together, top bars arranged in pairs and connecting the forward and rear corner bars together, arms pivoted at their forward ends to the forward corner bars and fitting between the members of the pairs of the rear corner bars, wheels journaled to the arms, and means for raising or lowering the rear ends of the arms and for holding the same in adjusted positions.
